When a new variant is added with the initial cost and initial quantity, the TradeGecko Stock on Hand value is increased but is not synced over to QBO/Xero automatically. The change in SOH will have to be manually adjusted in QBO/Xero. The reason for this is if you already have QBO or Xero prior to using TradeGecko, pushing the new SOH value from TradeGecko may fluctuate the already up-to-date SOH value in QBO/Xero.
